Dr Anastasios Georgoulas

Dr Anastasios Georgoulas is an Engineer devoted to Computational Fluid Dynamics (CFD), and in particular to the simulation of multi-phase flows, with specific interest in thermal management (boiling and cavitation, heat pipes) and Liquid Interface and Spray dynamics (droplet and bubble dynamics). His research interests, spread from fundamental topics such as the numerical simulation boiling/condensation and cavitation phenomena, focusing in the understanding of the underlined complex physics, to more applied fields like the numerical simulation two-phase heat transfer devices for industrial applications.

How I like to teach

Presently, I am involved in the teaching teams of ME101 (Design and Applications Project), ME248-ME250 (Mechanical and Manufacturing, Automotive and Aeronautical Instrumentation and Testing) and MEM01 (Major Team Project) modules but I also have years of experience in teaching Fluid Dynamics and Applied CFD from my previous activities before joining the university of 91¶¶Òõ.

I always begin my lectures focusing on the practical, everyday life applications of each subject, in order to highlight the necessity of the proposed knowledge acquirement. Furthermore, I always try to be very passionate and enthusiastic raising thus the interest on the topic. Finally, I always interact with the students during the lecture since I strongly believe that learning is a two-way coupled process.  

Since my research is in most cases directly related to the subjects that I teach, I always try to update my lectures with the most recent developments, practices and applications. This helps the students to better understand and love their future role as Engineers as well as to learn the basic principles that they need to follow designing or optimizing any industrial product or service in their future careers.

 

My research interests

My current research is devoted to the numerical simulation of multiphase flows with heat and mass transfer due to phase-change (boiling, condensation, cavitation) in both fundamental and applied levels. These research activities directly impact in a wide range of application fields in the automotive and aerospace sectors but also indirectly in other fields, like the pharmaceutical and biomedical sectors.

In the last years I have focused in the use of Open-source CFD tools (OpenFOAM) both for academic as well as for Industrial consultancy purposes, and within this context I have developed state of the art simulation tools for phase-change heat transfer and two-phase flow interface dynamics.

I am currently a member of the Advanced Engineering Centre (AEC) at the 91¶¶Òõ being a part of the research team that is led by Prof. M. Marengo, developing and utilizing novel CFD-based numerical modelling approaches for the simulation of complex two-phase flow and heat and mass transfer phenomena.

In the past I have been involved in a variety of National and International Research Projects and Industrial Consultancies that involved CFD Simulations of Multiphase Flows, Heat and Mass Transfer. Examples include:

  • CFD Simulation of cavitation in scroll expanders
  • CFD Simulation of turbidity currents in river outflows in the ocean, lakes and reservoirs
  • CFD-based design and optimisation of a passive heat removal system for LED head-lights
  • CFD-based design and optimisation of a passive heat removal system for LED lamps used as a main source of light in large commercial buildings.

Biography

I received a B.Eng. Degree of Civil Engineering in 2002 from the Department of Civil Engineering, Edinburgh Heriot-Watt University, Scotland, a M.Sc. Degree in Structural Engineering in 2003 from the Department of Civil Engineering, Edinburgh Heriot-Watt University, Scotland, a M.Sc. Degree in Hydraulic Mechanics in 2006 from the Department of Civil Engineering, Democritus University of Thrace, Greece and my Ph.D. degree from the Department of Civil Engineering Engineering, Democritus University of Thrace, Greece in 2010.

I have been a member of the Technical Chamber of Greece (TEE), since 2004. I have been involved in various national and international (European) research projects. I have worked as a Private Engineer/Consultant, as a Research Associate in the Democritus University of Thrace and as a Temporary Lecturer in Kavala Institute of Technology, in Greece.

On May 2013, I was appointed as a Marie Curie Fellow at the Laboratory of Thermal Physics, Department of Engineering, University of Bergamo (UNIBG), in Italy and from June 2014 up to May 2015 I was seconded to Caterpillar Inc (Peterborough, United Kingdom).

From June 2015 up to August 2015 I followed a short return-phase as a Marie Curie Fellow in UNIBG. From September 2015 I was appointed as a Senior Lecturer in Mechanical Engineering at the School of Computing, Engineering and Mathematics in the 91¶¶Òõ.
